Question 400577
The product {{{v*w}}} represents the income from sales of videos
(price/video) x (number of videos) = total income
{{{v*w = (2401 + 300j)*(31 + 2j)}}}
{{{v*w = 74431 + 9300j + 4802j  + 600*j^2}}}
{{{v*w = 74431 - 600 + 14102j}}}
{{{v*w = 73831 + 14102j}}}
In practical terms, there are amplitudes input and 
an amplitude output
{{{sqrt((73831)^2 + (14102)^2)}}} is the total income
